Answer 1

The best library for image processing with android (only arm support yet) is JavaCV, it's a Java interface for OpenCV which is the standard library for image processing in C++.

Here is an example of face detection in Android, with all the configuration hints for your AndroidManifest.xml.

EDIT : here is an example using contour detection.
